Harry Potter fans have already had a busy year full of new ways to revisit the stories they love. The critically acclaimed Audible Full-Cast Audio Editions gave listeners months of enjoyment and roughly a hundred hours of fresh performances.

At the same time, the first trailer for the upcoming HBO series arrived, building anticipation for its Christmas premiere.Now, ahead of that television adaptation, Bloomsbury Publishing is officially expanding the Pocket Potters line with two new books due in February 2027. These titles centre on three of Harry’s closest allies: Minerva McGonagall and the Weasley twins, Fred and George. Aimed primarily at younger readers, the books are also the kind of colourful, collectible releases that longtime fans who already own more Harry Potter merchandise than they need will still find hard to resist.

Two new guides to familiar faces

Pocket Potters: Fred and George, illustrated by Helen Brady, follows Hogwarts’ favourite troublemaking twins from their years of causing chaos at school to the creation of Weasleys’ Wizard Wheezes. The book will explore their best pranks and inventions, their talent for getting around the rules, and the spectacular decision to leave Hogwarts before opening their joke shop in Diagon Alley. Readers can expect plenty of references to Puking Pastilles, Extendable Ears, and other products that probably should never have been allowed near a classroom.

The twins’ energy and inventiveness have always stood out, and this volume gives those qualities a focused, illustrated stage.Pocket Potters: McGonagall, illustrated by Natalie Smillie, turns attention to the formidable Hogwarts professor. It will explore her role as Head of Gryffindor House, her ability to transform into a tabby cat, and the Transfiguration lessons that generations of students learned never to arrive late for.

The book also looks at McGonagall’s relationship with Harry and her fellow professors, her fierce loyalty to Hogwarts, and the dry sense of humour that often hid beneath that pointed hat.

Together the two titles bring supporting characters into sharper focus without rewriting the larger story.

A growing collection of pocket-sized stories

These new releases join the existing Pocket Potters books already available for Harry Potter, Ron Weasley, Hermione Granger, Professor Dumbledore, and Luna Lovegood.

Each volume is packed with quotes, key story moments, illustrations, and small facts designed to introduce young readers to the Wizarding World in a bright and approachable way. The format remains consistent across the series: short enough to read in one sitting, yet detailed enough to feel like a proper keepsake.

For children just discovering the books, they offer an easy entry point. For adults who grew up with the original novels, they provide a compact and colourful way to revisit favourite characters.

Timing that fits a larger revival

The February 2027 publication date arrives only a few months after the HBO series is scheduled to begin. With the Audible editions already giving fans a new audio experience and the television adaptation preparing to introduce the story to another generation, the Pocket Potters expansions keep the printed side of the franchise moving forward as well. Bloomsbury’s choice to highlight McGonagall and the Weasley twins rather than the central trio suggests quiet confidence that these supporting figures still have stories worth telling on their own.

For readers who first met them years ago, the books offer a compact return to familiar ground. For those just starting out, they provide another gentle doorway into a world that continues to grow.
